Thanks for the positive and helpful replies.
I wanted to report back with the eventual outcome, which is: success!!!
1. I went for a clean full windows 10 iso install. Yes, I know, there are some major issues with it. But, these last few weeks I've become somewhat an expert on making windows 10 act like a super powered windows 7 (had to pay a little, my 8 install was legit, BUT, it was an oem lic. and this is a new mobo/ssd).
2. I now have Sonar running, but I seem to have lost all my optimizations, so it's doing things like hitting processor 1 hard and choppy playback. So I'm going to have to re-do some of the settings. These are not major problems, just some occasional heavy usage times.
3. I now have a local
AND CONTINUOUS cloud backup. So this wont happen again. Using acronis.
4. This system is a hot rod, expect cool things.1>!>!>!>!!>!>

5. The only plugins I can't get licenses to work properly for are my ancient PSP wintage warmers, some kontakt libraries, and some free promo plugs I had picked up over the years - Waves one knob pumper comes to mind and some old cakewalk plugs that I liked.
